我需要使用“HTTP Post”与WebClient Post一些数据到特定的URL我有。
现在，我知道这可以用WebRequest完成，但由于某些原因，我想使用WebClient代替。这可能吗?如果是这样，谁能给我举个例子或者给我指出正确的方向?
当前回答
我刚刚找到了解决方案，是的，它比我想象的要简单:)
这就是解决方案:
string URI = "http://www.myurl.com/post.php";
string myParameters = "param1=value1¶m2=value2¶m3=value3";
using (WebClient wc = new WebClient())
{
wc.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
string HtmlResult = wc.UploadString(URI, myParameters);
}
它很有魅力:)

使用WebClient。UploadString或WebClient。UploadData可以轻松地将数据POST到服务器。我将展示一个使用UploadData的示例，因为UploadString的使用方式与DownloadString相同。
byte[] bret = client.UploadData("http://www.website.com/post.php", "POST",
System.Text.Encoding.ASCII.GetBytes("field1=value1&field2=value2") );
string sret = System.Text.Encoding.ASCII.GetString(bret);

下面是简单明了的答案:
public String sendSMS(String phone, String token) {
WebClient webClient = WebClient.create(smsServiceUrl);
SMSRequest smsRequest = new SMSRequest();
smsRequest.setMessage(token);
smsRequest.setPhoneNo(phone);
smsRequest.setTokenId(smsServiceTokenId);
Mono<String> response = webClient.post()
.uri(smsServiceEndpoint)
.header(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE)
.body(Mono.just(smsRequest), SMSRequest.class)
.retrieve().bodyToMono(String.class);
String deliveryResponse = response.block();
if (deliveryResponse.equalsIgnoreCase("success")) {
return deliveryResponse;
}
return null;
}
//Making a POST request using WebClient.
Function()
{
WebClient wc = new WebClient();
var URI = new Uri("http://your_uri_goes_here");
//If any encoding is needed.
wc.Headers["Content-Type"] = "application/x-www-form-urlencoded";
//Or any other encoding type.
//If any key needed
wc.Headers["KEY"] = "Your_Key_Goes_Here";
wc.UploadStringCompleted +=
new UploadStringCompletedEventHandler(wc_UploadStringCompleted);
wc.UploadStringAsync(URI,"POST","Data_To_Be_sent");
}
void wc__UploadStringCompleted(object sender, UploadStringCompletedEventArgs e)
{
try
{
MessageBox.Show(e.Result);
//e.result fetches you the response against your POST request.
}
catch(Exception exc)
{
MessageBox.Show(exc.ToString());
}
}
有一个内置的方法叫做UploadValues，它可以发送HTTP POST(或任何类型的HTTP方法)，并以适当的数据格式处理请求体的构造(用“&”连接参数并通过url编码转义字符):
using(WebClient client = new WebClient())
{
var reqparm = new System.Collections.Specialized.NameValueCollection();
reqparm.Add("param1", "<any> kinds & of = ? strings");
reqparm.Add("param2", "escaping is already handled");
byte[] responsebytes = client.UploadValues("http://localhost", "POST", reqparm);
string responsebody = Encoding.UTF8.GetString(responsebytes);
}
